BATTERY CONNECTION.

Application flled lune 16, 1920. Serial No. 889,895.

To all whom it may concem:

Be it known that I, JosEPHF. PRAX', a citizen of the United States, and resident of Rochester, in the county of Monroe and State of Newy York have invented-certain new and useful Improvements in Battery Connections, of which the following" is a specification. i

The present invention relates to a battery connection and more particularly to the manner of connecting a conductor terminal of the battery, an object of this invention beinggto rovide a connection which will give an e cient conducting'contact without the use of screws or solder while at the same time'being readily made or broken.

To this and other ends, theinvention consists of certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out ,in the appended claim.

In the drawings:

Fig. 1 is a sideview of the intermediate connecting member showing the conductor terminal attached .thereto;

Fig. 2 'is a plan view oftheparts shown Fig. 3 is a'side view, partially=,in section, of the conductor terminal;

Fig. 4 is an end view of the conductor terminal;

and a sma er'bore 6, the smaller bore being Fi 5 is a view, partially in section, showing the intermediate connecting member attached to the battery terminal; and

Fig. 6. is a side view, partially in section,

of the intermediate member connected to the battery terminal.

Referring morearticularly to-the drawings, 1 indicates t e battery, only a frag ment of which is shown. 2 indicates the battery terminal which is usually of cylindrical form. Secured to this battery terminal is an intermediate connectin member 3 preferably formed of lead an having an opening 4 extending therethrough, preferably near one side of the latter. Th s opening is adapted to receive the terminal 2 of the battery from either end thereof, so that either of the flat facesof the connectingmember may be disposed toward the battery. The connecting member is also provided with ano ening which has a large bore 5 eccentric to the axis of the large bore and preferably being formed by providing a renforcmgring 7 of copper, coated on all of its exposed faces by zinc. The axis of the large bore 5 is at right angles to the axis ofthe opening 4 so that the intermediate member 3 may have its connection withthe battery terminal 2 shifted in order that the conductor terminal may lead into the connection 3 from either side thereof. The conductor terminal is, in this instance, in

the form of a plug 8 in which the conductor 9 is inserted. This plug 8 is preferably formed of copper with an exterior coating of Z1110. It has an inner cylindrical por tion adapted to fit the bore 5 of the opening in the intermediate'member 3 and also has a reduced cylindrical portion 9 eccentricto the innercylindrical portion and adapted to fit the bore 6. By t is construction after the conductor terminal is fitted in the intermediate connecting member 3, it may be turned in either direction so as to cause a binding action between the conductor terminal and the intermediate connection 3. This rotary movement may be eflected by a suitable lnstrument introduced in any one of a number of openings 1'0 formed in the. periphery of an annular flange 11 on the conductor terminal at the inner end of the larger cylindrical portion of said terminal.

This invention ermits the conductor terminal to be rea 11y connected to the terminal of the battery without the use ofsolder or screws, and at the same time permits the ready disconnection of' such conductor terminal. I The intermediate member being reversible, and atthe same time connectmg with the battery terminal in such a manner that it may turn thereon about the axis of the terminal, permits the conductor. terminal. to connect with the battery-when leading from any direction.

What I claim as my invention and desire to secure by Letters Patent is:

A battery connection comprising a con-' ductor terminal having two external cylin- -drical portions, one of which is smaller thanand eccentric to the'other and is arran at the outer end of the terminal, there being provided a shoulder between the two cylinrical portions, and an intermediate con'- necting member-having an opening therein for thereception of the battery terminal and shoulder on the conductor terminal; said having an opening at right angles to andv vbores receiving the cylindrical portions of at one side of the first named opening. the conductor term n l and causing the 10 formed with two cylindrical bores, one of g' the 1315981: po q t io of 5 which is smaller .;than and eccentric to the the same 111 the p g 21 6 other, there being provided a shoulder bemember- Q tweenthe two bores for engagement by the JOSEPH- F. PRAX.
